Time display device and time display method thereof

Abstract

A time display device comprises a dial plate; a plurality of time indication portions set in the dial plate; and a plurality of groups of luminophors. Each of the groups of luminophors corresponds to a time indication portion, and comprises a first luminophor, a second luminophor, and a third luminophor. A clock unit provides current time information. A first switch unit electrifies/powers off the first luminophor. A second switch unit electrifies/powers off the second luminophor. A third switch unit electrifies/powers off the third luminophor. A hour hand controlling module obtains a hour value, and controls the first switch unit to electrify the first luminophor of the time indication portion corresponding to the obtained hour value. A minute hand controlling module obtains the current minute value, and controls the second switch and/or the third switch unit to electrify the corresponding luminophor.

1. A time display device comprising:
 a dial plate; 
 a plurality of time indication portions set in the dial plate, and configured for indicating a time; 
 a plurality of groups of luminophors, each of which corresponds to a time indication portion, and comprises a first luminophor, a second luminophor received by the first luminophor, and a third luminophor received by the second luminophor; 
 a clock unit configured for providing a current time information; 
 a first switch unit configured for electrifying/powering off the first luminophor; 
 a second switch unit configured for electrifying/powering off the second luminophor; 
 a third switch unit configured for electrifying/powering off the third luminophor; 
 a hour hand controlling module configured for obtaining a hour value from the provided current time information, and controlling the first switch unit to electrify the first luminophor of the time indication portion corresponding to the obtained hour value; and 
 a minute hand controlling module configured for obtaining the current minute value from the provided time information, and controlling the second switch and/or the third switch unit to electrify the corresponding luminophor. 
 
     
     
       2. The time display device as  claim 1 , wherein the first luminophor, the second luminophor and the third luminophor emit the same colors light. 
     
     
       3. The time display device as  claim 1 , wherein the first luminophor, the second luminophor and the third luminophor emit the different colors light. 
     
     
       4. The time display device as  claim 1 , wherein the third luminophor comprises a plurality of sub-luminophors, the number indicated by the second lumophor is obtained by multiplying the scale value of the second luminophor by 5, and the number indicated by the third luminophor is obtained as a sum of the number of sub-luminophors. 
     
     
       5. The time display device as  claim 4 , wherein the third switch unit comprises four sub-switches, and the minute hand controlling module divides the obtained minute by five to generate an integer quotient and a remainder;
 determines the time indication portion according to the integer quotient; and 
 controls the second switch unit to electrify the second luminophor of the determined time indication portion, and controls the sub-switches of the third switch unit to electrify the corresponding sub-luminophors of the third luminophor according to the remainder. 
 
     
     
       6. The time display device as  claim 1 , wherein the number of the plurality of time indication portion is twelve. 
     
     
       7. A time display method implemented by a time display device, which comprises a dial plate; a plurality of time indication portions set in the dial plate; a plurality of groups of luminophors, each of which corresponds to a time indication portion, and comprises a first luminophor, a second luminophor received by the first luminophor, and a third luminophor received by the second luminophor; the method comprising:
 providing a current time information; 
 obtaining a hour value from the provided current time information, and controlling the first switch unit to electrify the first luminophor of the time indication portion corresponding to the obtained hour value; and 
 a minute hand controlling module configured for obtaining the current minute value from the provided time information, and controlling the second switch and/or the third switch unit to electrify the corresponding luminophor. 
 
     
     
       8. The time display method as  claim 7 , wherein first luminophor, the second luminophor and the third luminophor emit the same colors light. 
     
     
       9. The time display method as  claim 7 , wherein the first luminophor, the second luminophor and the third luminophor emit the different colors light. 
     
     
       10. The time display method as  claim 7 , wherein the third luminophor comprises a plurality of sub-luminophors, the display device electrifying the second luminophor and the third luminophor step comprises:
 dividing the obtained minute by five to generate an integer quotient and a remainder; 
 determining the time indication portion according to the integer quotient; and 
 electrifying the second luminophor of the determined time indication portion, and electrifying the corresponding sub-luminophors of the third luminophor according to the remainder. 
 
     
     
       11. The time display method as  claim 7 , wherein the number of the plurality of time indication portion is twelve.
